KubeJS Generator

by Zizazr

Players who script recipes by hand can build them in a graphical editor inside KubeJS Generator, opened in-game with the K key.

FabricForgeNeoForgeClient required, server optionalAll rights reserved1.20.1 – 1.21.1

What it does

Players open the editor from the game and pick a recipe type, then fill in slots by clicking them and setting the item or tag, fluid, count and chance. Parameters for the chosen recipe sit in a side panel. When the recipe is finished, the export step checks the generated files and writes them as KubeJS scripts, so the result can be edited by hand afterward.

The layout describes slot positions and decorations, and a template string with slot and param placeholders tells the generator how to produce Java code for the type, hooked into the RegisterRecipeTypesEvent on the mod bus. The project is described as a development tool for modpack authors, server operators and anyone building custom recipes, and the full addon API reference is on its GitHub page. The mod requires KubeJS. Create, Mekanism and MoreJS: KubeJS Addon are optional companions that extend recipe support.

Key features

  1. Visual recipe editor

    Recipes are built in a graphical editor instead of by writing script text, with a search for the recipe type.

  2. Slot-based input

    Each slot takes an item or tag, a fluid, a count and a chance, set by clicking the slot in the editor.

  3. Script export

    The export step writes the finished recipes as KubeJS script files after showing the generated output for checking.

  4. Custom recipe types

    A JSON layout file lets third-party mods and datapacks add new recipe types with their own slots and parameters.
